For you guys that do mileage runs that aren't your home cities. Do you end up making nested reservations? two one-ways? Was considering doing the SEA-OSL MR but would need to fly EWR-SEA-EWR for the reposition. If i do it as a RT it will created a nested reservation, i know chances are I would be fine but not sure i really want to take a chance and have my return cancelled. I tried doing multi-city but the fare jumps pretty significantly.
